Greg, it seems to be a window of opprotunity from the 1st week of Oct to the 3 rd week of Oct here where I hunt. When the rut comes, my buck sightings slide down a little, but just before the rut comes is when I usually kill my better bucks. Last week of Oct actually. However, Im not good at hunting big bucks in the rut I guess, I can't seem to predict them at all.
